Seafood is an important source of nutrition, particularly in the developing world. An individual’s seafood consumption depends on the interaction of seafood production and various forms of access (geographic, social, institutional, etc.). Each of these can be affected by environmental change and variability, fisheries management practices, fishing behavior and economic wellbeing. Modelling provides one approach to link these environmental, socio-cultural, behavioral and nutritional aspects of fish demand. This project will build upon and improve an existing seafood economic model (AsiaFish) to produce seafood demand models for four African nations. Expanding the set of AsiaFish models geographically will allow for cross-country and cross-regional comparisons. Further, this project will improve accounting of small-scale (subsistence) fishing in the model in order to better incorporate the behavior and nutrition of some of the most vulnerable human populations. The resulting models will serve as useful management tools for connecting environmental change and variability to human nutrition, and for projecting changes in natural resource use driven by seafood demand. In this project the model will be applied to four scenarios: 1) changes in capture fisheries catch potential due to species distribution shifts; 2) rebuilding overharvested capture fisheries; 3) investment in aquaculture development; and 4) growing population and increasing per capita income. Comparing the resulting shifts in seafood consumption and natural resource demand among the range of scenarios and countries will test competing ideas about the interaction among the environment, fisheries, and human health in seafood-dependent, developing countries.
